WinCC VBScripting Practice: 28 Hands-On SCADA Examples

Practice 01 — Create Internal WinCC Tags

Build the WinCC tag database used by every later VBScript, SQL and reporting practical.

1. Open WinCC Explorer → Tag Management → Internal Tags.
2. Create the process tags below with names that match the SQL project.
3. Use Binary for status/commands, a floating-point type for process values, a 32-bit integer for IDs/SQF number, and Text for charge/event strings.

Practice 02 — Read a WinCC Tag Using VBScript

Read an actual process value from WinCC Runtime.

1. Create a button in Graphics Designer.
2. Open the button Mouse Click event and select VBScript.
3. Paste the script and start Runtime.

Dim Temp
Temp = HMIRuntime.Tags("Temp_Act").Read
MsgBox "Actual Temperature = " & Temp & " °C"

Practice 03 — Write a WinCC Tag

Write a command or setpoint from VBScript into a WinCC tag.

1. Create a test button.
2. Use the Write method on the required WinCC tag.
3. Verify the changed value in an I/O field or Tag Management diagnostics.

HMIRuntime.Tags("Temp_Set").Write 850
HMIRuntime.Tags("ChargeNo").Write "CHG-001"

Practice 04 — Start / Stop Motor Through Script

Control motor command tags from Graphics Designer buttons.

1. Create Start and Stop buttons.
2. Assign one script to each button.
3. Keep PLC-side permissives and safety logic authoritative in the controller.

' START button
HMIRuntime.Tags("Motor_Start").Write 1
HMIRuntime.Tags("Motor_Stop").Write 0

' STOP button
' HMIRuntime.Tags("Motor_Start").Write 0
' HMIRuntime.Tags("Motor_Stop").Write 1

Practice 05 — Analog Value Monitoring

Evaluate temperature, carbon potential, oil and jacket values in Runtime.

1. Read the actual process tag.
2. Compare it against defined operating limits.
3. Show an operator status or set a WinCC alarm/interlock tag.

Dim Temp
Temp = HMIRuntime.Tags("Temp_Act").Read

If Temp >= 900 Then
    MsgBox "Critical Temperature = " & Temp & " °C"
ElseIf Temp >= 850 Then
    MsgBox "High Temperature = " & Temp & " °C"
Else
    MsgBox "Temperature Normal = " & Temp & " °C"
End If

Practice 06 — Setpoint Entry

Accept an operator-entered setpoint and write it only when the input is numeric.

1. Read the current setpoint as the InputBox default.
2. Validate the returned string with IsNumeric.
3. Convert and write the value to Temp_Set.

Dim Value
Value = InputBox("Enter Temperature Setpoint", _
                 "SQF Temperature Setpoint", _
                 HMIRuntime.Tags("Temp_Set").Read)

If Value <> "" Then
    If IsNumeric(Value) Then
        HMIRuntime.Tags("Temp_Set").Write CDbl(Value)
    Else
        MsgBox "Please enter a numeric value."
    End If
End If

Practice 07 — IF / ELSE Process Logic

Use process conditions to make a WinCC decision.

1. Read setpoint and actual temperature.
2. Compare PV against SP.
3. Write the Temp_High status according to the result.

Dim TempSet, TempAct
TempSet = HMIRuntime.Tags("Temp_Set").Read
TempAct = HMIRuntime.Tags("Temp_Act").Read

If TempAct > TempSet Then
    HMIRuntime.Tags("Temp_High").Write 1
Else
    HMIRuntime.Tags("Temp_High").Write 0
End If

Practice 08 — Multiple-Condition Interlock

Combine temperature, CP and oil conditions into one process interlock.

1. Read all set and actual values.
2. Use OR conditions for abnormal states.
3. Set Process_Interlock and remove the start request when any limit is exceeded.

Dim TempSet, TempAct, CpSet, CpAct, OilSet, OilAct
TempSet = HMIRuntime.Tags("Temp_Set").Read
TempAct = HMIRuntime.Tags("Temp_Act").Read
CpSet = HMIRuntime.Tags("Cp_Set").Read
CpAct = HMIRuntime.Tags("Cp_Act").Read
OilSet = HMIRuntime.Tags("Oil_Set").Read
OilAct = HMIRuntime.Tags("Oil_Act").Read

If TempAct > TempSet + 30 Or _
   CpAct > CpSet + 0.2 Or _
   OilAct > OilSet + 10 Then
    HMIRuntime.Tags("Process_Interlock").Write 1
    HMIRuntime.Tags("Motor_Start").Write 0
Else
    HMIRuntime.Tags("Process_Interlock").Write 0
End If

Practice 09 — InputBox Operator Entry

Collect a charge number from the operator.

1. Open an InputBox from a button event.
2. Reject an empty response.
3. Write the accepted charge number to ChargeNo.

Dim Charge
Charge = InputBox("Enter Charge Number", "SQF Charge Entry")

If Charge <> "" Then
    HMIRuntime.Tags("ChargeNo").Write Charge
    MsgBox "Charge Number Updated: " & Charge
End If

Practice 10 — MsgBox Confirmation

Require operator confirmation before an action.

1. Create the confirmation message.
2. Check whether the operator selected Yes.
3. Execute the command only after confirmation.

Dim Answer
Answer = MsgBox("Do you want to start the SQF process?", _
                vbYesNo + vbQuestion, _
                "Process Confirmation")

If Answer = vbYes Then
    HMIRuntime.Tags("Motor_Start").Write 1
Else
    HMIRuntime.Tags("Motor_Start").Write 0
End If

Practice 11 — Screen Navigation

Navigate between WinCC process, trend and report pictures.

1. Confirm the target PDL picture names in Graphics Designer.
2. Assign the navigation script to menu buttons.
3. Test navigation in Runtime.

' Open process screen
HMIRuntime.BaseScreenName = "SQF_Process.pdl"

' Other examples:
' HMIRuntime.BaseScreenName = "SQF_Trend.pdl"
' HMIRuntime.BaseScreenName = "SQF_Report.pdl"

Practice 12 — Popup Handling

Open and close an equipment popup using a Picture Window object.

1. Create a Picture Window named PW_ProcessPopup.
2. Create the popup picture SQF_Popup.pdl.
3. Set PictureName and Visible from the VBScript event.

' Open popup
ScreenItems("PW_ProcessPopup").PictureName = "SQF_Popup.pdl"
ScreenItems("PW_ProcessPopup").Visible = True

' Close popup example:
' ScreenItems("PW_ProcessPopup").Visible = False

Practice 13 — Dynamic Object Properties

Change a graphic object at Runtime according to a WinCC tag.

1. Create a rectangle named RECT_TempStatus.
2. Read Temp_High.
3. Change visibility or another supported object property.

Dim AlarmState
AlarmState = HMIRuntime.Tags("Temp_High").Read

If AlarmState = 1 Then
    ScreenItems("RECT_TempStatus").Visible = True
Else
    ScreenItems("RECT_TempStatus").Visible = False
End If

Practice 14 — FOR Loop

Execute repetitive VBScript logic with a controlled loop.

1. Declare the loop counter.
2. Run the loop from 1 to 10.
3. Use HMIRuntime.Trace to observe execution in diagnostics.

Dim i
For i = 1 To 10
    HMIRuntime.Trace "WinCC VBScript Loop = " & i & vbCrLf
Next

Practice 15 — Date / Time Processing

Create SQL/report-friendly date and time values.

1. Use Now for the authoritative current date/time.
2. Build the legacy TM display string as HH:MM:SS.
3. Store DT as datetime2(3) in SQL Server and treat TM only as a display field.

Dim DT, TM
DT = Now
TM = Right("0" & Hour(Now), 2) & ":" & _
     Right("0" & Minute(Now), 2) & ":" & _
     Right("0" & Second(Now), 2)

MsgBox "DT = " & DT & vbCrLf & "TM = " & TM

Practice 16 — Error Handling

Prevent external communication errors from terminating the Runtime action without a useful diagnostic.

1. Enable On Error Resume Next only around the operation that may fail.
2. Check Err.Number immediately after the operation.
3. Report/trace the error, clear it and restore normal error handling.

On Error Resume Next

Dim Temp
Temp = HMIRuntime.Tags("Temp_Act").Read

If Err.Number <> 0 Then
    HMIRuntime.Trace "Error " & Err.Number & ": " & Err.Description & vbCrLf

WHERE name = 'SQF_DB';
GO

Practice 18 — Create dbo.tblEvent

Create the exact event/process table used by the WinCC VBScript examples.

1. Select SQF_DB.
2. Create dbo.tblEvent only if it does not already exist.
3. Keep DT as the authoritative datetime2(3) timestamp and TM as the legacy display value.

USE [SQF_DB];
GO

IF OBJECT_ID(N'dbo.tblEvent', N'U') IS NULL
BEGIN
    CREATE TABLE [dbo].[tblEvent]
    (

Practice 25 — Log Alarms into SQL

Store a high-temperature transition as an event record in tblEvent.

1. Use a one-shot/edge condition so one alarm transition produces one row.
2. Read the relevant process values.
3. Insert an event description such as HIGH TEMPERATURE ALARM.

Dim TempSet, TempAct
TempSet = HMIRuntime.Tags("Temp_Set").Read
TempAct = HMIRuntime.Tags("Temp_Act").Read

End If

Practice 26 — Log Production Data

Record charge/process transitions such as Charging → Heating.

1. Set ChargeNo, Event_From and Event_To from operator/process state.
2. Capture the current set/actual values.
3. Execute the same validated insert routine used in Practice 20 at the event transition.

HMIRuntime.Tags("ChargeNo").Write "CHG-2026-001"
HMIRuntime.Tags("Event_From").Write "Charging"
HMIRuntime.Tags("Event_To").Write "Heating"

' Then execute the validated tblEvent INSERT routine
' at the actual production state transition.
